Yeast cell size question

Hi Eleanor,

I can offer one general hint: tetraploid yeast cells are larger than  
diploids, and it may be possible to make cells of even higher ploidy. I  
did this long ago (~ 15 years!) to facilitate immunofluorescent  
detection of a low-abundance protein. Unfortunately I can't remember  
the details or references at this point (my own experiment didn't work  
so I never published it), but I think it was straightforward to make  
the polyploid cells - you just need a lot of markers to select them.

Good luck!
